Abstract

According to the electron diffraction studies on ordered alloys such as CuAu(II) (1), Cu3Pt (2), Ag3Mg (3), Cu3Pd (4), Au3Mn (5), Au4Zn (6) and Au3Zn (6), it was revealed that they possess superlattices consisting of anti-phase domains with definite size in a stable state. For example, CuAu(II) has a one-dimensional anti-phase domain structure characterized by the first kind of out-of-step, as shown in Fig. 1, while Cu3Pd has a two-dimensional anti-phase domain structure characterized by combination of the first kind and the second kind of out-of-step.
